Is this a decent strategy?

So I never play killer but still get them all and practise in custom games until I feel like I've got enough competence. As part of this confidence boosting, I started prestiging every killer by at least one level so I get their base level perks. Should I focus on doing this three times so I get level 3 of the perks I want the most (pain resonance for example) or just level the killer I want to main up individually and pray I get the perks I want instead?
